HEAT-RADIATOR FOR HOT-IR FURNACES.

SPECIFICATION forming part of Letters Patent No. 400,097, dated March 26, 1889.

Application filed September 20, 1888. Serial No. 285,856. (No model.)

T0 @ZZ whom it may concern.-

Be it known that I, CHARLES J. MANNING, a citizen of the United States, and a resident of the city of Utica, in the county of Oneida and State of New York, have invented certain new and useful Improvement-s in Heat-Radiators for Hot-Air Furnaces; and I do hereby declare that the following is a full, clear, and eX- act description of the invention, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form part of this specification.

My invention relates to an improvementin radiators for hot-air furnaces, and more particularly to radiators as set forth and described in Letters Patent of the United States, No. 308,614, dated December 2, 1384.

In the drawings which accompany and form part of this specification, Figure 1 shows the lower portion of a radiator and the diaphragmplate constituting my invention in position therein. Fig. 2 shows a perspective view of a radiator and a section of the inclosing-casing. Fig. 3 shows a vertical section of the device as shown in Fig. 2, on a .line through the center of two of the oval-shaped domes.

Referring to the drawings, 1 is the radiator having a central conical dome, 2, and four oval domes, 3, 3, 3b, and 3, radially arranged around the central dome and center of the radiator.

4 is the feed section or space directly over the fire-pot and fire, from which space 4 passage-ways open into the oval-shaped dome. Passage ways or ilues 5 5 and 6 6 are provided, uniting the domes. One of the passage-ways 5 is shown in full lines in Fig. 2, a vertical open section in Fig. 3, and the lower halves of both in Fig. 1. An end view of the flue 6 6 is shown in Fig. 3. Into the flue 6, uniting two of the oval domes, opens clean-out flue 7, Figs. 1, 2, and 3. Out of the remaining flue 6 opens smoke or draft flue 8. A casing, 9, and hot-air iiues 10 10 are provided for retaining and conducting the heated air.

In the oval domes adjacent to the smokeexit I provide diaphragm-plate 11 l1, iitting in the dome below the passage-ways connecting the several domes.

Diaphragm-plates 11 rest upon lugs 12 12 upon the inner surface of the oval dome, so that the dome and plate may expand and contract with the heat and cold indep endent1y,and without causing' strain or breakage of either by reason of unequal expansion and contraction. An opening or cut-away space, 13, is provided in the diaphragm-plates 11, adjacent to passage way or flue 5, to make a passage-way for the products of combustion that enter the domes, provided with diaphragm-plates from below as they move toward the smoke-exit.

'lhe operation of the radiator provided with diaphragm-plates, as described, is substantially as follows: The products of combustion as they arrive from the fire and pass toward the smoke-exit enter the several oval domes through the open bottoms. Those that have entered the domes more distant from thel smoke-exit as they move on pass through passage-ways 5 5 and into the domes nearer the smoke-exit above the diaphragm-plates. The products of combustion that have entered the domes nearer the smoke-eXit-zl e., those provided with diaphragm-plates-pass up under the plate 11 and then pass through opening 13 into the upper part of the dome. As the products of combustion pass up through openings 13, adjacent to the open ends of iiues 5, they are intermingled and commingled with the products passing through iiues 5, thus producing a more perfect combustion and radiation, which is an important feature involved in my invention. As the products of combustion pass on toward the smoke-exit from the upper chamber of the dome having the diaphragm-plates, they again and a second time unite and intermingle as they near the smoke-exit, thus completing a thorough and complete combustion and radiation. By constructing the opening 13 of proper size, a substantially equal amount of the products of combustion may be made to pass into and through each oval-shaped dome, and the radiator as a whole thus made more effective.

Of course more or less than four domes may be used, and more or less than two of them provided with diaphragm-plates, as described, and other modifications in the construction from that described may be made without departing from the spirit of my invention.
